Tire tread



FIG. 1 is a top plan view of a tire tread showing my new design which has been broken away in the middle to indicate indeterminate length it being understood that the tread pattern is repeated uniformly throughout its length;

FIG. 2 is a greatly enlarged fragmentary top plan view thereof;

FIG. 3 is a cross sectional view taken along line 3--3 in FIG. 2; and

FIG. 4 is an enlarged perspective view thereof formed into a ring as it would appear attached to a tire carcass. 

The ornamental design for a tire tread, as shown and described.
